まとめ

脊髄静脈直径と門脈直径の比率は0. 7以上で,小児の腹腔鏡手術後の門脈血栓症を予測する. この比率は高いリスクを持つ子どもを特定し監視や予防措置を講じることができます

科学分野:

小児外科
血管外科
放射線科

背景:

ポータル静脈栓塞 (PVT) は,腹腔鏡手術 (LS) の後の潜在的な合併症である.
発症リスクが高い子どもを特定することは早期の介入に不可欠です

研究の目的:

LSを受ける子供におけるPVTの予測要因を特定する.
脊髄静脈直径 (SVD) と門静脈直径 (PVD) の測定がPVTを予測する有用性を評価する.

主な方法:

LSを受けた21人の小児患者の遡及レビュー.
PVT患者とPVT患者との間での手術前と手術中のデータの比較
手術前CTスキャンを用いて,PV結合からの複数の点でのSVDの測定とSVD/PVD比の計算.

主要な成果:

PVTの患者は高齢で,女性の方が多く,BMIが高かった.
PVT患者では,SVDとPVDの比率が著しく高かった.
SVD/PVD比はPVTの最も信頼できる予測指標で,最適なカットオフ値は0. 7でした.

結論:

SVD/PVD比 ≥0. 7は,小児のLS後にPVTの強い予測因子である.
術前のSVD/PVD比の測定は,高リスク患者を特定することができます.
この比率は,PVTの発生率を減らすためのより厳密な監視と予防戦略を導くことができます.

Hepatic Portal System

8.2K

The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Esophageal Varices-I: Introduction

2.4K

Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Esophageal Varices-II: Clinical Features and Management

884

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Portal Hypertension

Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
